Series 300 Basic Hydraulic Valves

General Description

The Dorot Series 300 valves are automatic, hydraulically activated by the pressure of the pipeline, diaphragm actuated, globe and angle pattern control valves. This valve is designed for use in any water supply application, including the controlling of water flow for deluge, pre-action or foam-water type fire protection sprinkler systems. The valve consists of three major components: the body, the cover, and the diaphragm assembly. The only moving part is the diaphragm assembly. Pack-less construction and simplicity of design of the valve assure long service life, reliable operation and low maintenance.

Features

UL-listed with a wide range of control trims Fast opening and cushioned closure operation Reliable drip-tight shut off Simple and reliable design Easy installation and maintenance Double or single chamber actuation High-grade construction materials Regulation from near zero flow Low pressure losses at high flow rates

Water Level Control Valves

FL Modulating Float Controlled Valve

The main valve is controlled by a float valve, located in the tank or reservoir and set at the required maximum water level. The valve maintains the maximum level continuously.

Features:

Accurate level control. Simple and reliable design Easy installation and maintenance The application is based on the UL listed valves

30-FL

FLEL Electric Float Controlled Valve

An electric sensor float, located in the tank\reservoir, sends a command to a solenoid controlled valve. The main valve will fully open when the solenoid is activated and closes drip tight when the solenoid is de-energized, thus enabling accurate and reliable differential level control. Optional Addition: Surge-Preventing Closure.
